RELATED REQUESTS
The present application claims priority pursuant to 35 5 USC § 119 on the German Patent Application No. 10 2011 085.509.2, filed on October 31, 2011 and the German Utility Model Application No. 20 2012 000 163.9, filed on January 10, 2012. Full disclosures of these documents are expressly incorporated by reference herein.
FIELD OF THE INVENTION
The present invention relates to a substantially emulsifier-free cosmetic or dermatological aqueous preparation comprising at least about 13% by weight of microcrystalline wax and a ratio of lipophilic perfume to lipophobic ingredients of about 0.5: 1 to about 4: one. The preparation is suitable for application on wet skin and therefore allows it to be used while a person is showering and confers a sensory impression of essences both during and after shower use, and has a long-lasting effect. duration and can be easily perceived by the consumer.
BACKGROUND OF THE INVENTION
Cosmetic preparations or divided based on their application time. Some products are immediately after their dermatological application and can be removed by washing (removal by use
<img file="MX337016B_D0010.tif" />
rinsed), others are intended to remain long on the skin and be effective on it (permanent).
Cosmetic skin care preparations were developed primarily for use on dry skin. This form of preparations are known as permanent preparations, such as creams, lotions, body milk. Often these emulsions, in particular emulsions, or / w / w.
are formulated as W / O, 0 / W, O / W / O or
Emulsions are understood to generally refer to heterogeneous systems comprising two liquids that are immiscible or only miscible to a limited extent and are usually called phases. In an emulsion, one of the two liquids is dispersed as very fine drops in the other liquid. Liquids (pure or as solutions) are present in an emulsion in a more or less fine distribution, which is generally stable only to a limited extent.
If the two liquids are water and oil and oil droplets are present in a finely dispersed form in water, then this is an oil-in-water emulsion (0 / W emulsion, eg milk). The basic character, for example, electrical conductivity, sensory properties, the ability to form a continuous staining phase, of a 0 / W emulsion, is defined by water. In the case of a water-in-oil emulsion (W / 0 emulsion, for example butter), the principle is reversed, the basic character being determined in this case by the oil.
Permanent preparations are not suitable for your
<img file="MX337016B_D0011.tif" />
use on wet or damp skin. Due to those present, they can emulsify water and, due to lipids, optionally leave behind an oily film.
Instead, preparations that are removed by rinsing are designed for use under the shower or during the bath.
A long-term impression of essences can also be conferred with the prior art preparations by only two different products applied successively. To experience impressions of essences during the shower, the user is referred, for example, to scented shower gels, although the impression of essences of these is lost after the shower. Subsequently, the user only achieves a long-lasting impression of essences thanks to a scented cream and / or a perfume.
Therefore, many cosmetic series include various products with the same perfume that have to be applied successively, such as shower gels, deodorant preparations and / or eau de cologne.
On the other hand, the preparations that are removed by rinsing involve the care aspect obtained after rubbing the cream to a lesser extent.
It is desirable to provide a preparation that confers an impression of essences both while in the shower and afterwards, without applying a second product.
A property of cosmetic products that is very important to the consumer but can only be measured quantitatively with difficulty is its texture and sensorization. The term texture is understood to mean those properties of a cosmetic that can be attributed to

OF THE PROPERTY
INDUSTRIAL the constitution of the preparation, perceirs'e * Ttrecrfáftte<sup>1</sup> A sense of feel and touch and optionally expressed in terms of mechanical or rheological flow properties. The texture can be tested in particular by sensorisation.
The texture of cosmetic products, which optionally can be influenced with the help of additives, is practically of the same importance for the consumer, since its effects can be established objectively.
The term sensorization refers to the scientific discipline 10 that tries to evaluate cosmetic preparations based on sensory impressions. The sensory evaluation of a cosmetic is done by reference to visual, olfactory and haptic impression.
• Visual impressions: all the characteristics that can be perceived through the eyes (color, shape, structure).
• Olfactory impressions: all the impressions of essences that can be perceived after breathing the air through the nose, which can often be differentiated into an initial smell (top note), main essence (central note, body) and later essence (note of background, base note). The top note, the center note and the base note together form the total odor impression of the perfume. Volatile substances are only released after use and also contribute to the olfactory impression.
• Haptic impressions: all sensations of the sense of touch, which are fundamentally related to the constitution and consistency of the product.

INDUSTRIAL integrally. The disadvantages of sensory analysis are the subjectivity of the impression, the ease with which the test subjects can be influenced and the considerable dispersion of the results caused as a consequence.
This weakness is now counteracted using groups of qualified test subjects, with mutual protection of the testers and statistical evaluation of the analytical data, for the most part exhaustive.
SUMMARY OF THE INVENTION
In view of the foregoing, an objective of the present invention was to provide preparations which, apart from the usual criteria for cosmetics, such as compatibility, storage stability and the like, also offer hitherto unknown essential cosmetic benefits to the consumer. In particular, the sought-after preparations should be suitable for use in the body care sector, that is, for application to the whole body and, at the same time, be sensory and especially olfactory attractive.
In principle, the different known forms of application, such as shampoo, bath and shower gel, shower gel, deodorant, antiperspirant, permanent preparations, pose different requirements in the perfume. In the case of a bath and shower gel, the perfume must smell pleasantly under the shower, that is, at temperatures up to approximately 40 ° C. The temperature stability and evaporation of the perfume ingredients led to limited selection options. In this case, the impact of the mass is the main objective. Adherence

-6 Particularly durable essence beyond the shower process until now was not required and / or was not easily adjustable. This is especially the case since the hydrophilic / lipophilic ingredients of the perfume are removed by rapid rinsing with water and optionally surfactants. To achieve a prolonged scent effect, lipophilic perfume ingredients, such as essential oils, would have to be incorporated, which are not so easily washed off. As is known, however, lipophilic substances lead to instabilities of the overall preparations, due to the change in the ratio of emulsifier to lipids and, therefore, often cause oil separation.
Therefore, another objective of the present invention was to provide a stable product that does not require the presence of emulsifiers inside. This was particularly difficult in view of the fact that the perfumes used contain a high percentage of lipophilic components (for example, more than 30% by weight).
In contrast, for permanent products with a long-lasting essence impression, the challenges they faced were quite different. According to experience, particular attention is paid to the base note and the base note of the perfume to lengthen the impression of the essence.
Perfume ingredients must emphasize the care and cosmetic character of the permanent product. In this case, a prolonged duration of the perfume ingredients on the skin is mandatory and desired.
It is also an object of the present invention

DETAILED DESCRIPTION OF THE INVENTION
The particular issues shown in this document are by way of example and for the purpose of illustrative analysis of the embodiments of the present invention only, and are presented to provide what is believed to be the most useful and easy to understand description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show the structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, making the description apparent to those skilled in the art how the various forms of the present invention can be put into practice.
The preparation according to the present invention is substantially free of (conventional) emulsifiers. In this regard, it is noted that the term emulsifier as used herein and in the appended claims does not include polyacrylic acid polymers having emulsifying properties, polymers which may be comprised in component (iv) of the preparation. Instead, a preparation according to the present invention preferably comprises at least one polyacrylic acid polymer that has emulsifying properties. In other words, apart from the polyacrylic acid polymer or polymers, no further emulsifiers are present in the preparation according to the invention in any

INDUSTRIAL significant (emulsifier) concentration Y''Í5e 'IhdlCJ in addition to the term substantially, relative to emulsifier-free is intended to indicate that the preparation does not contain any emulsifier or combination of emulsifiers in a concentration which would result in a remarkable emulsion. Accordingly, the concentration of the emulsifier or emulsifiers in the present preparation, if present, will normally not be more than about 0.02%, for example, not more than 0.01% or not more than 0.001% by weight, based on the total weight of the preparation (not including any polyacrylic acid polymers or polymers that may be comprised in component (iv)).
The preparation of the present invention comprises both lipophilic and lipophobic perfume ingredients. The weight ratio of the lipophilic perfume ingredients to the lipophobic ingredients is from about 0.5: 1 to about 4: 1.
Formulation outside this range has been found to produce a different perfume impression of the product. This then is not recognizable while showering and / or cannot be perceived for a long time after showering. The preparation according to the invention now allows for the first time a long-lasting essence that is easily perceptible to the consumer, which is to be transmitted both after application under the shower and also afterwards. This is the main difference from the known shower preparations, which only smell during the shower and do not allow a long-term effect of the essence, and normal body creams, whose

b. the essence during the shower is not noticeable but a long-term effect is present; me
c. the stability of the preparation is affected.
Examples of preferred lipophilic perfume ingredients for use in preparing the present invention include 1- (1,2,3,4,5,6,7,8-octahydro-2,3,8,8tetramethyl-2- naphthyl) ethan-l-one, 1,2,3,4,5,6,7,8-octahydro2,3,8,8-tetramethyl-2-acetonephthalenone (ISO E Super), hexyl salicylate, dihydromyrcenol, geraniol , methyl dihydrojasmonate (Hedione), isoeugenol, Sandela (CAS No. 70955-71-4), butylphenyl methylpropional, linalyl acetate, citronellol, amyl salicylate, methylionone, orange oil, bergamot oil, patchouli oil, peppermint oil, rose oil and lavender oil. They can be used alone or in a combination of two, three, four or more lipophilic perfume ingredients.
A lipophilic perfume ingredient is defined herein as a perfume ingredient with a solubility in water of 20 ° C of not more than 0.01 mol / 1. For example, hexyl salicylate (CAS No. 6259-76-3) has a solubility in water at 20 ° C of approximately 9 mg / 1 and dihydro-myrcenol (CAS No. 18479-58-8) has a solubility in 25 ° C water of approximately 252 mg / 1 (= approximately 0.0016 mol / 1).

They can be used alone or in combination of two, three, four or more lipophobic perfume ingredients. For example, lipophobic perfume ingredients may comprise hexyl salicylate and / or may comprise or consist of (A) Iso E Super, hexyl salicylate and dihydromyrcenol, or (B) hedione, dihydromyrcenol and methylionone), or (C) geraniol , linalool and hexyl salicylate.

previously exposed.
Often components (i) and (ii) such as, for example, a combination of any of (A), (B) and (C) with any of (D), (E) and (F), will be present in a total concentration of at least about 0.4% by weight, for example, at least about 0.5% by weight or at least about 0.6% by weight, but usually not more than about 1 .5% by weight, for example, not more than about 1.2% by weight or not more than about 1.0% by weight.
Regarding component (iii) of the preparation of the present invention, microcrystalline wax is a generic term and alternative names for it include mineral wax [German: Mikrokristalline Wachse, French: Cire Minerale]. Microcrystalline wax (mineral wax) is a type of wax produced by the de-lubrication of petrolatum, as part of the oil refining process. In contrast, with the more familiar paraffin wax that contains mostly unbranched allones, microcrystalline wax contains a higher percentage of isoparaffinic (branched) hydrocarbons and naphthenic hydrocarbons. It has finer crystals than paraffin wax. Predominantly, it consists of high molecular weight saturated aliphatic hydrocarbons having more than 35 carbon atoms in the molecule. Generally, it is darker, more viscous, denser, more adherent and more elastic than paraffin wax and has a higher molecular weight and melting point. The elastic and adhesive characteristics of microcrystalline wax are related to the non-linear chain components it contains. The crystal structure of the
<img file="MX337016B_D0026.tif" />
<img file="MX337016B_D0027.tif" />
Typical microcrystalline wax is small and fine, making it more flexible than paraffin wax. A microcrystalline wax that is suitable for use in the present invention has CAS No. 63231-60-7 (I EINECS / EILINCS No. 264-038-1).
Microcrystalline wax, when produced by wax refiners, is normally produced to meet a number of ASTM specifications such as freezing point, needle penetration, color, and viscosity. Microcrystalline wax can generally be classified into laminate grades and hardening grades. Laminate grades typically have a melting point of 60-80 ° C (140-175 ° F) and a needle penetration of 25 or higher. The melting point of the hardening grades will normally vary from approximately 8093.3 ° C (175-200 ° F) and the needle penetration of these will normally be 25 or less. Both grades are suitable for use in the present invention.
Microcrystalline wax is derived from the refining of heavy distillates from the production of lubricating oils. This by-product must then be de-lubricated in a wax refinery. Depending on the end use and the desired specification, the odor can then be removed from the product and its color can be removed. This is normally done by a filtration method or by hydrotreating the wax material.
Microcrystalline wax for use in the present invention will normally be subject to higher quality standards. Microcrystalline wax for use in the present invention will normally be substantially free of, for example, polycyclic aromatics, compounds containing
-19ΙΝ!
MEXICAN TITLE OF PROPERTY
INDUSTRIAL sulfur and other allergens such as, for example, crop protection agents. Due to its chemical neutrality, microcrystalline wax does not have an allergenic potential. The allergic reactions triggered by microcrystalline wax are so far unknown. Compared to animal or vegetable oils, microcrystalline wax has a high oxidation stability, that is, it does not become rancid and does not require additional stabilizers. Therefore, microcrystalline wax and therefore also preparations containing it also require no or relatively small amounts of additional preservatives.
The skin care properties of microcrystalline wax are primarily found in the area of skin moisture. The microcrystalline wax forms a partially occlusive protective film on the skin that protects it against drying. This is very important, particularly in the case of dry skin or highly stressed skin with a barrier of damaged skin. Partially occlusive hygienic products place themselves in the upper callus layer and thus reduce transepidermal water loss. In combination with skin moisturizers (eg, glycerol), they help to quickly restore skin balance. It is observed that very similar mixtures of substances, the so-called mineral waxes, are naturally present in relatively large quantities also in various vegetable waxes (for example, candelilla wax) and insect waxes (for example, beeswax).
Microcrystalline wax is present in the preparation

INDUSTRIAL

of the present invention in a concentration of at mc-noo · about 13% by weight, for example, at least about 14% by weight, at least about 15% by weight, or at least about 16% by weight , and will normally be present in a concentration of not more than about 40% by weight, for example, not more than about 35% by weight, not more than about 30% by weight, or not more than about 25% by weight .
The preparation according to the present invention can be used as a two-in-one product under the shower and combines, in addition to the shower, at the same time, the rubbing application of the cream.
The microcrystalline wax in the preparation according to the invention was found to bind to the skin during the showering process. In this way, a pleasant sensation is achieved on the user's skin. The lipophilic constituents of the perfume bind particularly well and thus ensure a particularly lasting impression of essence.
Due to this combination of perfume using microcrystalline wax, apart from the short-term impression of essence during the shower, a long-term impression of essence is also ensured.
It has been found that only with an amount of at least about 13% by weight of microcrystalline wax can a sensory attractive, long lasting, detectable film be achieved on the skin which is necessary for perfume bonding.
At higher fractions, particularly above

<img file="MX337016B_D0030.tif" />
about 35% by weight, the texture is longer spread more easily, and it's like a cream. The higher the concentration of microcrystalline wax, the greater the consistency or solidity as well, although this may be desired in individual preparations.
Therefore, the microcrystalline wax fraction is advantageously chosen to be at most about 35% by weight, in particular at most 30% by weight based on the total weight of the preparation. If component (vi) is also present (which is preferred), the total concentration of components (iii) plus (vi) will normally not be more than about 60% by weight, for example, not more than about 45 % by weight, not more than about 40% by weight or not more than about 35% by weight.
The preparation according to the invention allows for the first time the application of a hygienic product under the shower.
The preparation of the present invention preferably also comprises at least two (eg two, three, four or more, preferably at least three) different polyacrylic acid polymers, i.e. polyacrylic acid polymers that differ from each other with respect to minus one of its properties.
The term "polyacrylic acid polymers" as used herein and in the appended claims denotes the acrylic acid and / or methacrylic acid polymers as well as acrylate crospolymers known in cosmetics. Preferably, it includes polymers (macromolecules) with a high molecular weight (> 1 mg / mol) that comprise a
-22 MEXICAN PROPERTY INSTITUTE
INDUSTRIAL basic structure of polyacrylic acid and small amounts of polyalkenyl ether crosslinks. They are also called carbomers. Carbomers are divided, for example, into types A, B, and C. They differ, for example, by forming gels with different viscosities (United States Pharmacopeia, USP). These water soluble or dispersible polymers can cause a significant viscosity increase in the liquid in which they dissolve or disperse. This is caused by the formation of carbomer microgels in the water.
Other preferred polyacrylic acid polymers for use in the present invention include acrylate crospolymers that exert a polymeric emulsifying effect. Polymeric emulsifiers are primarily high molecular weight acrylic acid polymers. These emulsifying polyacrylic acid polymers comprise a small lipophilic fraction in addition to the main hydrophilic part. Within the context of the present invention, acrylate crospolymers are preferred which have the INCI name acrylate / C10-30 alkyl acrylate crospolymer. Representatives thereof are available, for example, under the tradenames Pemulen® TR-1 and Pemulen® TR-2 and also Carbopol® 1342, Carbopol® 1382 and Carbopol® ETD 2020 from NOVEON. Acrylates / Alkyl Acrylate Crospolymers
C10-30 preferred for use in the present invention include
Pemulen® TR-1 and Carbopol® 3128 from Lubrizol.
A preferred combination of polyacrylic acid polymers for use in the present invention includes a polyacrylic acid polymer with an emulsifying effect, such as Pemulen® TR-1 combined with other acid polymers.

polyacrylic, such as Carbopol® 3128, which improve the sensory properties and ensure the stability of the preparation (especially at elevated temperatures) and the combination with free water.
Particular preference is given to a combination of (at least) three polyacrylic acid polymers, i.e. (A) (at least) one polyacrylic acid polymer having an emulsifying effect such as, for example, Pemulen® TR-1 or Pemulen® TR-2, combined with (b) (at least) a polyacrylic acid polymer that improves sensory properties and ensures the stability of the preparation, especially at elevated temperatures (for example, Carbopol® 3128) and (c) (at least) a polyacrylic acid polymer that improves sensory properties by absorbing free water (eg Carbopol® 981). Merely by way of example, component (iv) of the preparation according to the present invention may comprise a total of from about 0.05% to 1% by weight, for example, from about 0.09% to about the 0.25% by weight of (a) plus (b) (for example, in a weight ratio of about 2: 1 to about 1: 2, such as about 1: 1) and about 0.05% at about 1% by weight, for example from about 0.01% to about 0.03% by weight of (c). For example, the preparation may comprise a combination of (1) from about 0.08% to about 0.15% by weight of Pemulen® TR-1 (and / or Pemulen® TR-2), (2) of about 0.08% to about 0.15% by weight of Carbopol® 3128 and (3) from about 0.01% to about 0.03% by weight of Carbopol® 981.
<img file="MX337016B_D0032.tif" />
<img file="MX337016B_D0033.tif" />
Component (iv) will normally be present in the preparation of the present invention, if any, in a (total) concentration of at least about 0.05% by weight, for example, at least about 5 0.1 % by weight, at least about 0.15% by weight, or at least about 0.2% by weight, but usually not more than about 1% by weight, for example, not more than about 0.5 % in weigh, not more than about 0.3% by weight or not more than about 0.25% by weight.
The polyacrylic acid polymers of component (iv) may also differ in the viscosities they provide. For example, when measured in a 0.2 wt% solution at 25 ° C with a Brookfield RVT or RVF at 20 rpm with a No. 5 spindle 15, Pemulen® TR-1 shows minimal emulsion viscosity / maximum of 6,500 / 15,500 mPas, while the corresponding values for Carbopol® 1342 are 4,000 / 11,000 mPas.
With respect to the optional, though preferably present, component (v) of the preparation of the present invention, C14-22 fatty alcohols denote fatty alcohols having a carbon number of 14 to 22, for example, 14, 16, 18, 20 or 22 carbon atoms. The fatty alcohols are preferably selected from linear (saturated) fatty alcohols and, in particular, from one or more than 25 myristyl alcohol (Οι<sub>4</sub>Η<sub>30</sub>Ο), cetyl alcohol (or palmityl alcohol) (C16H34O), stearyl alcohol (or alcohol (Ci8H<sub>38</sub>O) and cetyl-stearyl alcohol (alcohol a mixture of predominantly cetyl alcohol (hexadecanol) and stearyl alcohol (octadecanol), (CAS No. 8005-44-5).

The preparation advantageously comprises' al maiiuj. C14-22 fatty alcohols and, in particular, at least one C fatty alcohol<sub>i4</sub> (C14), at least one Ci fatty alcohol<sub>8</sub> (C18) and at least one mixture of Ci6 / Ci fatty alcohol is present<sub>8 </sub>(C16 / C18), preferably, in each case only one C14 fatty alcohol, one Ci fatty alcohol<sub>8</sub> and / or a mixture of fatty alcohol C<sub>16</sub>/ Ci<sub>8</sub>. If only two fatty alcohols are to be used, the C14 fatty alcohol is preferably absent.
Normally, fatty alcohols C<sub>14</sub>-<sub>22</sub> will be present in the preparation of the present invention, if at all, in a total concentration of at least about 3% by weight, for example, at least about 4% by weight, at least about 5% by weight, at least about 6% by weight, or at least about 7% by weight, but not more than about 14% by weight, for example, not more than about 13% by weight, not more than about 12% in weigh, not more than about 11% by weight, not more than about 10% by weight or not more than about 9% by weight, based on the total weight of the preparation.
The weight percentages of fatty alcohols will often be from about 0.5% to about 2.5% by weight for C14 (C14) alcohol or fatty alcohols, from about 1.5% to about 4, 0% by weight for C18 (C18) fatty alcohols and from about 3.5% to about 6% by weight for C16 / C18 (C16 / 18) fatty alcohols, based on the total weight of the preparation.
For example, the fatty alcohols optionally contained in the preparation of the present invention may comprise or

consist of (1) from about 0.5% to about 2.0% by weight of myristyl alcohol, (2) from about 1.5% to about 3.5% by weight of stearyl alcohol, and ( 3) from about 3.5% to about 6% by weight of cetearyl alcohol. Component (1) may optionally be absent.
The combination of at least two polyacrylic acid polymers and at least two C14-22 fatty alcohols aids in stabilizing the preparation of the present invention. If only one representative of the polyacrylic acids and fatty alcohols is selected in each case, the stability tends to be inadequate and, in particular, the sensation on the skin after application to wet / damp skin tends to be unpleasant, waxy, rough and scratchy.
In addition to components (i) to (v), the preparation of the present invention preferably also comprises component (vi), i.e. one or more hydrocarbon oils. A preferred hydrocarbon oil for use in the present invention includes medicinal white oil, also called liquid paraffin. Medical white oils are mixtures of substances that have a variable composition depending on the origin. For example, products that have been obtained from geologically old Venezuela oil are particularly rich in naphthenes (cycloalkanes).
In contrast, geologically young North Sea oil is low in naphthenes and predominantly comprises acyclic compounds.
Naphthene-rich mineral oils only occur in exclusive areas of the world (Venezuela, Saudi Arabia, Russia).
They are difficult to obtain and therefore expensive. The

. . -i ii ·. ii vwwy r ^ 'yrra ^ gftililiOTWi i · ——— · - low naphthene mineral oils are easier to obtain and are often classified as having good value. A disadvantage of low naphthene mineral oils is that these oils, or mixtures with these oils with, among others, crystalline wax used in emulsions, destabilize the emulsions, resulting in severe oil separation.
Naphthenes or alicyclic hydrocarbons are ring-shaped hydrocarbons. The naphthene content of crude oil is generally 5%, in the case of Russian oil it is often higher than this, and in the case of American oil below this value. Naphthenes have a higher bond stress than paraffins in the molecular structure and therefore have a higher heating value.
Cycloalkanes (cycloparaffins) are saturated ring-shaped hydrocarbons of the general formula C<sub>n</sub>H2n (n = 3, 4, 5 ..) whose names are formed from the corresponding alkane and the prefix cyclo-. The cycloalkanes, among others, cyclopentene and cyclohexane, which exist in oil are also called naphthenes. Preferably, the naphthalene-containing medicinal white oil is used in the preparation of the present invention.

The weight ratio of component (iii): component (vi) is preferably from about 3: 1 to about 1: 1, for example, from about 1.5: 1 to about 2.5: 1.
In many cases, a sensory attractive, long-lasting, and detectable film on the skin will be obtained only when the combined concentration of components (iii) plus (vi) is at least about 20% by weight. At total concentrations above 60% by weight the preparation can often no longer be easily dispersed and turns into a cream. The higher the total concentration of (iii) plus (vi), the greater the consistency and / or solidity as well, although this may be desired in specific preparations. |
In this sense, it is observed that the mixtures of components (iii) and (vi) are sometimes also called microcrystalline wax, mineral wax or petrolatum (now registered under the trade name CheseBorough Ponds). However, as used herein and in the appended claims, the term microcrystalline wax exclusively denotes component (iii), that is, without component (vi).
The preparation according to the present invention

preferably there is also its substantially<sup>=</sup>*^'‘<sup>,</sup>I cried about surfactants. In other words, one or more surfactants are preferably present, if at all, in a concentration that does not markedly reduce surface tension. Typically, total surfactant concentrations, if any, in the preparation of the present invention will not be greater than about 0.02%, for example, not more than 0.01% or not more than about 0.001% in weight, based on the total weight of the preparation.
Surfactants are substances that reduce the surface tension of a liquid or the interfacial tension between two phases and allow or support the formation of dispersions. Surfactants enable two liquids that are not truly miscible with each other, such as, for example, oil and water, to disperse.
Additionally, surfactants are described as amphiphilic substances that are capable of dissolving non-polar organic substances in water. As a result of their specific molecular structure with at least one hydrophilic and one hydrophobic molecular residue, they provide a reduction in the surface tension of water, the wetting of the skin, facilitate the removal and dissolution of dirt, and facilitate the removal by rinsing and, if desired, for foam regulation.
The hydrophilic residues of a surfactant molecule are mainly polar functional groups, for example, COO, -OSC> 3<sup>2</sup>~, -SO3, while hydrophobic residues are generally non-polar hydrocarbon radicals. Surfactants are generally classified according to .1 _

type and charge of the hydrophilic molecular moiety. In relation to this, four groups can be distinguished:
• anionic surfactants, • cationic surfactants, • amphoteric surfactants, and • nonionic surfactants.
Anionic surfactants generally have carboxylate, sulfate, or sulfonate groups as functional groups. In an aqueous solution, they form negatively charged organic ions in an acidic or neutral medium. Cationic surfactants are characterized almost exclusively by the presence of a quaternary ammonium group. In an aqueous solution, they form positively charged organic ions in an acidic or neutral medium. Amphoteric surfactants contain both anionic and cationic groups and consequently behave like anionic or cationic surfactants in aqueous solution depending on pH. In a strongly acidic medium, they have a positive charge and in an alkaline medium they have a negative charge.
Additionally, detergent substances such as, for example, cationic surfactants, in particular quaternary ammonium compounds, are known. A detergent substance is used in laundry detergents, dishwasher detergents , shampoos, shower gels and refers to the fraction of the formulation that influences washing or cleaning performance. Detergent substances increase the solubility of grease and dirt particles in water that adhere to the laundry or to the body. They can be of natural or synthetic origin. They can be differentiated into anionic, cationic, ampholytic or nonionic, depending

of the nature of their cargo. <sup>1</sup>
Emulsifiers allow two immiscible liquids (for example, oil in water) to combine to give an emulsion. Due to their amphiphilic character, they penetrate the oil with the rest soluble in fat. As a result of the hydrophilic moiety, the drop of oil that is now formed by stirring can be dispersed in the aqueous environment. Emulsifiers mainly do not have a detergent character that reduces surface tension.

The viscosity of a preparation of the present invention will normally not be less than about 1,000 mPas, for example, not less than about 2,000 mPas, not less than about 3,000 mPas or not less than about 3,500 mPas, but usually not more than about 10,000 mPas , for example, not more than about 8,000 mPas, not more than about 7,000 mPas, not more than about 6,000 mPas or not more than about 5,500 mPas, as measured at 25 ° C 24 hours after preparing the preparation by a rotational rheometer such as, for example, the Rheomat R 123 apparatus from proRheo GmbH, Germany (# 1 spindle).
The preparation of the present invention can be used advantageously particularly on wet or damp skin (and also for shaving (wet)). In particular, the preparation can be used while taking a shower or bath and after cleansing the skin / body. After applying the preparation, rinse with water and dry the skin, for example, with a towel, all necessary to obtain the skin care effect of the preparation. Some parts of the preparation are left behind on the skin in a similar way to when a cream is applied to the skin. In other words, the preparation can be used as a balm similar to the use of a hair conditioner.
